The previously rumored Healthbook iOS 8 app has been confirmed, although that may not be its actual name. However, an app like the Healthbook app that was recently described does exist and will help users keep track of their health and fitness information, but also help “boost the ecosystem of health app developers and health wearable makers.” In the future, the app may “evolve into a repository for health and fitness information,” and even “provide feedback and analysis of that data,” if allowable by regulators.
